The bear was probably ok, the car wasn't going more than 20 mph and the bear rolled up on top of the hood a little bit, which means the energy wasn't directed entirely into the bear, or car. Adrenaline can get yu a long way in those situations, but only if your body is capable of getting the **** out of there, and that bear looked big enough and left the road quick enough that it seems like he's going to have this lesson to learn from for a while.
